A Historic Temperature Surge
With just two months left, 2024 is “virtually certain” to become the hottest year ever recorded, according to the Copernicus Climate Change Service. For the first time, global temperatures are set to exceed 2.7°F (1.5°C) above pre-industrial levels, a key threshold in international climate agreements. This milestone underscores the severity of global warming and the urgency of climate action as world leaders prepare for COP29 in Azerbaijan.
Samantha Burgess, Deputy Director of Copernicus, emphasized the significance of this development. “This should act as a wake-up call, urging greater action ahead of COP29,” she stated.
The previous record for the hottest year, set in 2023, will be surpassed as 2024’s first ten months have already shown unprecedented warmth.
Record-Breaking Heat in the U.S.
October 2024 was exceptionally warm in the United States, with a national average temperature of 59°F—nearly 5°F above the 20th-century average. It was the second-warmest October on record, only behind 1963, according to NOAA.
Several states, including Arizona, New Mexico, Texas, and Utah, reported their warmest Octobers ever. Other states, such as California and Colorado, experienced above-average temperatures. In addition, Delaware and New Jersey recorded their driest October, escalating fire risks.
Wildfires have intensified across the country, with notable incidents like the Mountain Fire in California and fires reaching as far as Brooklyn, New York. The dry conditions have only exacerbated the severity of these blazes.
A Global Perspective: Heatwaves and Alarming Trends
Globally, October’s average surface temperature was 2.97°F (1.65°C) above pre-industrial levels, marking the 15th consecutive month of temperatures exceeding 2.7°F above historical norms. Since June 2023, global temperatures have consistently surpassed this critical benchmark.
Over the past year, global temperatures also exceeded the 1991-2020 average by 1.3°F (0.7°C), highlighting the continuing upward trend in warming. This data, collected from satellites, weather stations, and other sources, confirms the escalation of global temperatures.
The only way 2024 wouldn’t set a new heat record is if the next two months revert to pre-industrial averages—an increasingly unlikely scenario given current trends.
A Call to Action
The escalating heat and its devastating environmental impacts serve as a stark reminder of the need for urgent action. As COP29 approaches, world leaders face mounting pressure to adopt stronger climate policies and accelerate efforts to reduce emissions.
“The rise in global temperatures is more than a statistic,” Burgess stated. “It’s a reminder of the immediate and long-term challenges we face.”
The 2024 data underscores the critical need for coordinated global action to meet climate goals and mitigate the worst effects of global warming.
